Abstract

During the rabi season of 2015-16, a field experiment was carried out in Junagadh, Gujarat, on calcareous clayey soil to investigate the impact of phosphorus and sulphur levels on yield and economics of wheat (Triticum aestivum L.). In terms of available nutrients, the soil had low levels of nitrogen (242 kg ha-1), medium levels of phosphorus (39.20 kg ha-1), high levels of potash (292 kg ha-1), and medium levels of sulphur (19.05 ppm). Applying 90 kg P2O5 ha-1 (P3) produced maximum spike length (8.7 cm), number of spikelets spike-1 (15.9), grain yield (4451 kg ha-1), straw yield (6886 kg ha-1) and B: C ratio (2.08), which was found to be comparable to P2 (60 kg P2O5 ha-1). These experimental results were reported in the results of the study. Applying 40 kg S ha-1 was found to be equivalent to applying 20 kg S ha-1 and resulted in a significant increase in the number of spikelets spike-1 (15.8), spike length (8.6 cm), grain yield (4354 kg ha-1), straw yield (6809 kg ha-1) and B:C ratio of 2.00. Grain yield was significantly higher (4937 kg ha-1) with the combined application of 90 kg P2O5 ha-1 + 40 kg S ha-1 (P3S2) than with the control (P0S0).

Conclusion

Based on the findings of a year-long field study, it seems reasonable to conclude that irrigated wheat (GW 496) should be fertilized with 90 kg P2O5 ha-1 + 40 kg S ha-1 along with a nitrogen dose based on 120 kg N ha-1 in order to increase yield and net realization.
